NFPA 85 Boiler and Combustion Systems Hazards Code: Learn from the Experts on Boiler and Furnace Safety

NFPA 85 Boiler and Combustion Systems Hazards Code

NFPA 85 is a standard published by the National Fire Protection Association (NFPA) that provides guidelines for the safe operation of boilers and combustion systems. Boilers are devices that generate steam or hot water by burning fuel, while combustion systems are processes that use fuel and air to produce heat or power. Both boilers and combustion systems can pose hazards such as explosions, implosions, fires, and toxic emissions if not properly designed, installed, maintained, and controlled.

The NFPA 85 standard covers boilers with a heat input capacity greater than 12.5 million Btu per hour (MMBtu/h), pulverized fuel systems, and heat recovery steam generators (HRSGs). The standard also applies to multiple burner boilers, stokers, atmospheric fluidized bed boilers, and waste heat boilers. The standard does not cover boilers used for domestic or space heating purposes, nor does it cover fire tube boilers, water tube boilers with a steam production not exceeding 45.4 kg/s (3600 lb/h), or electric boilers.

The NFPA 85 standard consists of four chapters and nine annexes. The chapters cover general requirements, single burner boilers, multiple burner boilers, and HRSGs. The annexes provide explanatory material, references, definitions, combustion control system diagrams, sample calculations, inspection checklists, and a guide for boiler and combustion systems hazards analysis.

The NFPA 85 standard aims to prevent boiler and combustion system accidents by specifying the minimum requirements for the design, installation, operation, maintenance, and testing of these systems. The standard also addresses the human factors involved in boiler and combustion system safety, such as training, supervision, communication, and emergency procedures. The standard emphasizes the importance of a comprehensive safety program that includes hazard identification, risk assessment, risk reduction, and risk management.

The NFPA 85 standard is updated periodically to reflect the latest technology, research, and experience in boiler and combustion system safety. The most recent edition of the standard was published in 2023. Some of the changes in the 2023 edition include:

Revised definitions of terms such as boiler purge, flame detector, flame failure response time, fuel valve proving system, interlock test switch, master fuel trip valve, pilot valve proving system, purge credit time, and purge timer.

Added requirements for fuel valve leak testing for single burner boilers.

The NFPA 85 standard is a valuable resource for boiler and combustion system owners, operators, engineers, contractors, inspectors, and regulators. The standard provides the minimum requirements for ensuring the safe and efficient operation of these systems, as well as preventing potential hazards that could result in loss of life, property, or environment.
